Heat-induced morphological changes in silver nanowires deposited on a patterned silicon substrate
Beilstein J. Nanotechnol. 2024, 15, 435–446, doi:10.3762/bjnano.15.39
- Abstract Metallic nanowires (NWs) are sensitive to heat treatment and can split into shorter fragments within minutes at temperatures far below the melting point. This process can hinder the functioning of NW-based devices that are subject to relatively mild temperatures. Commonly, heat-induced
- agreement with the experimental observations. Our finding suggests that heat-induced fragmentation of metallic nanowires in general cannot be purely explained by the commonly accepted Rayleigh instability model, but should include effects related to the interaction with the substrate. Single Ag NW suspended
Density functional theory study of Au-fcc/Ge and Au-hcp/Ge interfaces
Beilstein J. Nanotechnol. 2023, 14, 1093–1105, doi:10.3762/bjnano.14.90
- differences between the polytypes are very small [14][25]. In contrast, molecular dynamics simulations of metallic nanowires show a phase transformation from fcc to hcp below a critical diameter [26]. These findings support the feasibility of obtaining new hexagonal structures under conditions where surface

- |Δ| in superconducting nanowires one finds [5]: where Rξ is the normal-state resistance of the wire segment of length equal to the superconducting coherence length ξ and Rq = 2π/e2 ≃ 25.8 kΩ is the quantum resistance unit. For generic metallic nanowires one typically has Rξ ≪ Rq, implying that

High-yield synthesis of silver nanowires for transparent conducting PET films
Beilstein J. Nanotechnol. 2021, 12, 624–632, doi:10.3762/bjnano.12.51
- , carbon nanotubes (CNT), conductive polymers, and metallic nanowires, have been tested commercially as alternative to ITO films for flexible optoelectronic devices [6][7][8][9]. Amongst them, graphene and carbon materials, particularly CNTs, display low optical transparency and high sheet resistance owing
Magnetism and magnetoresistance of single Ni–Cu alloy nanowires
Beilstein J. Nanotechnol. 2018, 9, 2345–2355, doi:10.3762/bjnano.9.219
- also related to an exchange length parameter, λex = π√(A/K), where A is the exchange stiffness and K is the anisotropy constant, respectively. Even for single-component metallic nanowires (e.g., Ni) of high aspect ratio, different magnetization reversal mechanisms might be in work (from the simplest

Beilstein J. Nanotechnol. 2018, 9, 271–300, doi:10.3762/bjnano.9.29
- size depends on elastic properties: (1) increase in the Young’s modulus of metallic nanowires relative to the bulk value of the metal, as their diameters are reduced (e.g., Ag and Pd [107][108][109] nanowires); (2) decrease of Young’s modulus with decreasing size, for example, for Cr nanocantilevers

- is still very much prevalent today. The main advantages of using CNTs to produce metallic nanowires is that the CNTs act as a template for self-assembly of the nanowires [40][41] and the CNT structure can act as a protective sheath to protect the nanowire from being damaged by chemicals in harsh

- processes which could be used as a scale-up process for patterning metal–nanotube contacts. For instance, Vazquez-Mena et al.

- mesoscale metal wires have attracted considerable attention due to their potential application in new electronic, sensor, and optical devices [1][2][3][4][5][6][7][8][9][10]. Furthermore, metallic nanowires and -contacts play a key role as leads and contacts for contacting molecules in the field of
